Fans of the Animorphs

I'm not sure how active this community is anymore, but I thought I'd give this a shot. So, I've had this t-shirt design idea in my head for AGES now (I kid you not, it really has been years now) that I finally want to bring into production. I have pretty much all the quotes and little images for it all set, but I just have one thing left to bring it all together that I need to get figured out and I was wondering if you guys could help me with it. If there could be one image for the entire Animorphs series, what would it be to you? Like a simple icon (think how for Apple computers there's just that iconic apple, but I guess fandom-wise it could be like how Star Wars fans could see a silhouette of Darth Vader's mask or the Death Star and know it's for Star Wars or Harry Potter fans could see a snitch or a sorting hat or something). I kind of just want a silhouette shape that Animorphs fans when they see the quotes or something along with it their brains go "Ah, Animorphs :)" Right now I've been designing with the silhouette of a hawk, but I just wanted to see if anyone else had any ideas. Other things that kind of crossed my mind was a cube shape (for the morphing box), an Andalite silhouette, or that A in the Animorphs font. I think I like the hawk silhouette best though so far (perched or flying though?).
